The ->move operation has two bugs:
- It is called with the same extension as source and destination,
so it doesn't update the new extension.
- The address of the old extension is calculated incorrectly,
instead of (void *)ct->ext + ct->ext->offset[i] it uses
ct->ext + ct->ext->offset[i].

TCP connection tracking in netfilter did not handle TCP reopening
properly: active close was taken into account for one side only and
not for any side, which is fixed now. The patch includes more comments
to explain the logic how the different cases are handled.
The bug was discovered by Jeff Chua.

In a few instances, we need to remove the chunk from the transmitted list
prior to freeing it. This is because the free code doesn't do that any
more and so we need to do it manually.

While recevied ASCONF chunk with serial number less then needed, kernel
will treat this chunk as a retransmitted ASCONF chunk and find cached
ASCONF-ACK chunk used sctp_assoc_lookup_asconf_ack(). But this function
will always return NO-NULL. So response with cached ASCONF-ACKs chunk
will cause kernel panic.
In function sctp_assoc_lookup_asconf_ack(), if the cached ASCONF-ACKs
list asconf_ack_list is empty, or if the serial being requested does not
exists, the function as it currectly stands returns the actuall
list_head asoc->asconf_ack_list, this is not a cache ASCONF-ACK chunk
but a bogus pointer.

Thomas Dreibholz has reported that port numbers are not filled

When we recieve a FORWARD_TSN chunk, we need to reap
all the queued fast-forwarded chunks from the ordering queue
However, if we don't have them queued, we need to see if
the next expected one is there as well. If it is, start
deliver from that point instead of waiting for the next
chunk to arrive.

According to the bluetooth HID spec v1.0 chapter 7.4.2
"This code requests a major state change in a BT-HID device. A HID_CONTROL
request does not generate a HANDSHAKE response."
"A HID_CONTROL packet with a parameter of VIRTUAL_CABLE_UNPLUG is the only
HID_CONTROL packet a device can send to a host. A host will ignore all other
packets."

identifier
If SCTP-AUTH is enabled, received AUTH chunk with BAD shared key
identifier will cause kernel panic.
Test as following:
step1: enabled /proc/sys/net/sctp/auth_enable
step 2: connect to SCTP server with auth capable. Association is
established between endpoints. Then send a AUTH chunk with a bad
shareid, SCTP server will kernel panic after received that AUTH chunk.
SCTP client SCTP server
INIT ---------->
(with auth capable)
<---------- INIT-ACK
(with auth capable)
COOKIE-ECHO ---------->
<---------- COOKIE-ACK
AUTH ---------->
AUTH chunk is like this:
AUTH chunk
Chunk type: AUTH (15)
Chunk flags: 0x00
Chunk length: 28
Shared key identifier: 10
HMAC identifier: SHA-1 (1)
HMAC: 0000000000000000000000000000000000000000
The assignment of NULL to key can safely be removed, since key_for_each
(which is just list_for_each_entry under the covers does an initial
assignment to key anyway).
If the endpoint_shared_keys list is empty, or if the key_id being
requested does not exist, the function as it currently stands returns
the actuall list_head (in this case endpoint_shared_keys. Since that
list_head isn't surrounded by an actuall data structure, the last
iteration through list_for_each_entry will do a container_of on key, and
we wind up returning a bogus pointer, instead of NULL, as we should.

If STCP is started while /proc/sys/net/sctp/auth_enable is set 0 and
association is established between endpoints. Then if
/proc/sys/net/sctp/auth_enable is set 1, a received AUTH chunk will
cause kernel panic.
Test as following:
step 1: echo 0> /proc/sys/net/sctp/auth_enable
step 2:
SCTP client SCTP server
INIT --------->
<--------- INIT-ACK
COOKIE-ECHO --------->
<--------- COOKIE-ACK
step 3:
echo 1> /proc/sys/net/sctp/auth_enable
step 4:
SCTP client SCTP server
AUTH -----------> Kernel Panic

git broken build)
The 2.6 latest git build was broken when using the following
configuration options:
CONFIG_NET_EMATCH=n
CONFIG_NET_CLS_FLOW=y
with the following error:
net/sched/cls_flow.c: In function 'flow_dump':
net/sched/cls_flow.c:598: error: 'struct tcf_ematch_tree' has no
member named 'hdr'
make[2]: *** [net/sched/cls_flow.o] Error 1
make[1]: *** [net/sched] Error 2
make: *** [net] Error 2
see the recent post by Li Zefan:
http://www.spinics.net/lists/netdev/msg54434.html
The reason for this crash is that struct tcf_ematch_tree
(net/pkt_cls.h) is empty when CONFIG_NET_EMATCH is not defined.
When CONFIG_NET_EMATCH is defined, the tcf_ematch_tree structure
indeed holds a struct tcf_ematch_tree_hdr (hdr) as flow_dump()
expects.
This patch adds #ifdef CONFIG_NET_EMATCH in flow_dump to avoid this.

It seems that virtio_net wants to disable callbacks (interrupts) before
calling netif_rx_schedule(), so we can't use the return value to do so.

now returns void, rather than a boolean.

Previously we used a type/len pair within the config space, but this
seems overkill. We now simply define a structure which represents the
layout in the config space: the config space can now only be extended
at the end.

1) We indicate what fields are present with an explicit feature bit.
2) Virtqueues are explicitly numbered, and not in the config space.

This way we can remove TCP and DCCP specific versions of
sk->sk_prot->get_port: both v4 and v6 use inet_csk_get_port
sk->sk_prot->hash: inet_hash is directly used, only v6 need
a specific version to deal with mapped sockets
sk->sk_prot->unhash: both v4 and v6 use inet_hash directly
struct inet_connection_sock_af_ops also gets a new member, bind_conflict, so
that inet_csk_get_port can find the per family routine.
Now only the lookup routines receive as a parameter a struct inet_hashtable.
With this we further reuse code, reducing the difference among INET transport
protocols.
Eventually work has to be done on UDP and SCTP to make them share this
infrastructure and get as a bonus inet_diag interfaces so that iproute can be
used with these protocols.
